Just got my M-LOK upper from Moriarti. As my first order, I was a bit nervous of what I was going to receive. I'm happy to report that I got this beautiful upper in today. Tight, solid construction. All functionality is flawless. I couldn't be happier.

Got this item the other day installed it in seconds. Love the looks of it. Shot with it yesterday and was again very pleased. Whole transaction was fast and easy. Very happy with this purchase

I received this, love the way it looks, I could not mount a MOE Magpul Picatinny rail to this M-LOK system on this upper. So I opted for a MOE vertical grip that didn't require the rail.

Just received order. Was not a quad rail.

No complaints though, came with all parts and no missing screws

Used with Aero stripped lower. No issues so far.
